β-1 and β-2-Adamantylaspartates, H-Asp(O-1-Ada)-OH and H-Asp(O-2-Ada)-OH respectively, were synthesized and their properties examined, showing their possible application in solid-phase peptide synthesis when used in combination with the fluoren-9-ylmethoxycarbonyl (Fmoc) group, as an Nα-protecting group; both these new protecting groups can suppress aspartimide formation as a side reaction under acidic
分别合成了β-1和β-2-金刚烷黄酮酸酯,H-Asp(O-1-Ada)-OH和H-Asp(O-2-Ada)-OH,并考察了它们的性能,表明它们在固体中的可能应用-PHASE肽合成结合所述芴-9-基甲氧羰基(FMOC)基团,作为N使用时α -保护基团; 在酸性和碱性条件下,这两个新的保护基都可以抑制天冬酰胺的副反应。
